A broad surface high pressure over the central Atlantic will continue to promote moderate to locally fresh easterly winds through tonight. As a result, small craft should continue to exercise caution. Over the weekend and into early next week, a surface trough will gradually weaken these winds. At the same time, a deep trough to the west of the region will support an unsettled weather pattern, with a high chance of thunderstorm development through at least Saturday. These storms could lead to locally higher winds and seas. In addition, hazy conditions are likely over the next few days due to the presence of Saharan dust. $$ AMZ711-171015- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 507 PM AST Fri May 16 2025 .TONIGHT...East winds 10 to 15 knots with gusts up to 20 knots.
